System and method for efficient allocation of resources in virtualized desktop environments

A computer readable storage medium comprising a computer readable program for managing responsiveness of virtual desktops using passive monitoring, wherein the computer readable program when executed on a computer causes the computer to:

• measure a time between an interactive desktop event and a result of the interactive desktop event, wherein the measuring a time includes comparing a screen state or event with a library of events stored in memory and employing the screen state or event to determine a start time and an end time for the interactive desktop event;
• and
• reallocate system resources to improve responsiveness time.

A method for managing responsiveness of virtual desktops using passive monitoring, comprising:

• measuring a time between an interactive desktop event and a result of the interactive desktop event and employing the time to determine a probability that a virtual component will remain active or idle, wherein the measuring a time includes comparing a screen state or event with a library of events stored in memory and employing the screen state or event to determine a start time and an end time for the interactive desktop event;
• and
• based on the probability, migrating workload in accordance with the probability that resources will remain active or idle to improve responsiveness.

A system for managing responsiveness of virtual desktops, comprising:

• a control system configured to receive responsiveness feedback and to reallocate system resources in accordance with the feedback, the control system being implemented in a computer device with memory storage, and comprising:
• an allocation controller configured to receive responsiveness measurements based upon information about interactive desktop events and to receive resource utilization measurements to determine how to allocate resources to improve responsiveness, and
• a library of events stored in memory wherein a display screen is monitored to determine and compare displayed information with the library to determine a start time and an end time for an interactive desktop event.
